Reminder to record call

1

Welcome and role call

@Bruce Goldberg

• Request for more direct involvement of group members in identifying topics for discussion and development and testing of concept models

2

After and due to

@Bruce Goldberg

• Discussion ensued as to whether "due to" implies after

  • Likely the case for traumatic injuries (after traumatic event)

  • Need evaluation for other combined disorders

• @Bruce Goldberg to test moving Due to (attribute) under After (attribute)

• @Bruce Goldberg to find examples where due to may not imply after and where after may not imply due to
  
  
  

• General agreement that after and due to should remain distinct

• Use due to, after or due to and after based on FSNs

  • Exceptions

    • 239182004 |Skin graft hematoma (disorder)|

      • Due to 304040003 |Grafting to skin (procedure)|. Should be after 04040003 |Grafting to skin (procedure)| (+/- Due to)

    • Disorders due to exposure to substance events

      • Model as after exposure + causative agent substance

3

Fetal/maternal modeling

@Phil Brown

• @Phil Brown to test a new attribute to associate fetal/maternal states with procedures

• @Phil Brown demonstrated in an author test task the use of a new attribute, Recipient period with a range of 450426006 |Fetal or neonatal period (qualifier value)| to define procedures on the fetus occurring during different stages of pregnancy

• Advantages include identification of duplicate concepts and being able to sufficiently define current intermediate primitives

• @Phil Brown to continue to pursue this area

Pregnancy/labor/delivery function observables

@Bruce Goldberg

• Proposal to inactivate these

• Pregnancy_labor_delivery_ puerperium function observables.pptx

• Tabled for a future call

5

Modeling of hemorrhage

@Bruce Goldberg

• Hemorrhage as a disorder vs. finding

• Finding site of hemorrhage

• Main discussion - Finding site for hemorrhage of X (disorder)

  • X (body structure)

    • Advantage - simplicity

•  

  • Y Blood vessel of X (body structure) if blood vessel is part of body structure

  • 2 role groups: Damage + Y blood vessel structure and hemorrhage + X (body structure) if bleeding is into a space

    • Advantage - aligns with ICD-11 which interprets hemorrhage as blood vessel disorder.

    • Disadvantage - requires much work

  • @Yongsheng Gao to:

    • Determine which hemorrhage of X concepts not modeled with Y Blood vessel of X (body structure)

    • Investigate how to determine which hemorrhage of X concepts refer to spaces

• Hemorrhage of blood vessel (disorder) vs. Bleeding (finding) needs further evaluation

Non-traumatic brain injuries and stroke

@Bruce Goldberg

• Concern voiced over losing causative condition as a parent.

  • Needs more discussion

  @Bruce Goldberg to retest model of 724994008 |Cerebral ischemic stroke due to stenosis of extracranial large artery (disorder)| using due to 1055001 |Stenosis of precerebral artery (disorder)| 

• Cerebral ischemic stroke due to stenosis of extracranial large artery.pptx

• Tabled for a future callTabled for a future call

Botulism

@Bruce Goldberg

• Proposed model for botulism and subtypes

• Botulism.pptx

• Tabled for a future call
